No own theory: I have seen pictures of Dieter with this accordion, I
know, that there is no electrical musical instrument (and no computer!)
in Dieters private house, and finally because he told it officially in
an interview, I did with him in the mid of the nineties for the german
mag "KEYS", which can be read on http://www.doepfer.de/hist_d.htm

"Dieter Döpfers erster Kontakt mit der Musikwelt versprach auch sein
letzter zu werden: Der Vater machte Akkordeonstunden zur Pflicht und
Sohnemann lernte den Tastenbalg spielen und hassen."
